(author), Mohammadi, Mohsen (author)This study explores the evolution of solidification microstructure of a laser powder bed fusion (L-PBF) martensitic stainless steel during solution annealing and aging. Quasi in-situ experiments using electron backscatter diffraction (EBSD) revealed that the finer, more equiaxed microstructure below the melt pool was susceptible to...journal article 2024

Shakerin, Sajad (author), Sanjari, Mehdi (author), Pirgazi, H. (author), Amirkhiz, Babak Shalchi (author), Mohammadi, Mohsen (author)Maraging steel (MS1)-tool steel (P20) bimetals additively manufactured using the laser powder bed fusion technique were studied under different heat treatment cycles and loading conditions. The hardening of P20 and aging of MS1 were performed sequentially on the hybrid samples. The interfacial characteristics and microstructural evolution of...journal article 2022

(author), Mohammadi, Mohsen (author)In this work, the effect of heating rate on the phase transformation temperatures was investigated using dilatometry analysis. Continuous heating and isothermal holding above Ac<sub>3</sub> temperature on microstructural evolutions in additively manufactured (AM) parts of Fe-Cr-Ni maraging stainless steel were studied. The microstructural...journal article 2022
